Description
This application claims priority from United Kingdom Patent Application No. 08 10 985.2, filed 17 Jun. 2008, and from United Kingdom Patent Application No. 09 10 097.5, filed 12 Jun. 2009, and the entire disclosure of each is incorporated herein by reference in their entirety.
The present invention relates to a chair.
Static chairs are known. Static seating restricts movement and can have a detrimental effect on the body when used for extensive periods of time. Other chairs that have been designed to combat this issue have involved highly complex mechanisms and have not achieved the desirable level of fluidity of movement and responsiveness for this application.
According to an aspect of the present invention, there is provided a chair comprising: a seating portion for occupation; a base portion for location upon a support surface; and a connecting portion connectedly extending between the seating portion and the base portion. The connecting portion is configured to provide a degree of freedom of the position of the seating portion relative to the base portion, such that the seating portion is movable between a default unloaded position relative to the base portion and each of a plurality of available loaded positions relative to the base portion. When unoccupied, the seating portion is in the default unloaded position relative to the base portion, and when occupied, the seating portion is in one of the plurality of available loaded positions relative to the base portion. The chair is configured to dynamically respond to changes in the posture of an occupant.
A first view of a chair 101 is shown in FIG. 1 . Chair 101 comprises seating portion 102, base portion 103 and connecting portion 104. Seating portion 102 is for occupation and in this embodiment is made from moulded plastic and any suitably shaped component could be used. Base portion 103 is in this embodiment substantially circular and is provided to locate the chair on a support surface such as a floor. In alternative embodiments differing base portions could be used provided that they offer a suitable degree of stability to the chair, for example a different configuration is shown in FIG. 5 .
Connecting portion 104 connectedly extends between seating portion 102 and base portion 103. In this embodiment, connecting portion 104 comprises a plurality of elongate members. In this example, there are three elongate members although alternative numbers could be used in alternative configurations. In this embodiment, the elongate members are constructed from resilient material, in this example reinforced plastic. Suitable materials include GRP (Glass-Fibre Reinforced Plastic) or CRP (Carbon-Fibre Reinforced Plastic). Any other materials that share similar strength, flex and material memory properties are suitable.
The connecting portion 104 is configured to provide a degree of freedom of the position of the seating portion 102 relative to the base portion 103. This means that the seating portion 102 is moveable between different positions relative to the base portion depending upon whether the chair is occupied and the chair is configured to dynamically respond to changes in posture of an occupant. When it is unoccupied, the seating portion 102 is in a default unloaded position relative to base portion 103. When the chair is occupied, the seating portion is moveable between a plurality of available loaded positions relative to the base portion. Because of the configuration of the connecting portion 104, the relative positions of seating portion 102 and base portion 103 are able to adjust in response to movements of the occupant. Therefore, the chair provides an active seating solution in contrast with other chairs, which are static. In addition, in the present embodiment the connecting portion 104 is configured to return to the default unloaded position as an occupant vacates the chair.
A front view of chair 101 is shown in FIG. 2 . Again seating portion 102 and base portion 103 can be seen along with connecting portion 104 which comprises a plurality of elongate members. In this example there are three elongate members labelled as rod 201, rod 202 and rod 203. Rod 201 is attached to seating portion 102 at point 204, rod 202 is attached to seating portion 102 at 205 and rod 203 is attached to seating portion 102 at 206. These attachment points 204, 205 and 206 are substantially in front of the centre of gravity of the load when the chair is occupied.
In addition, there is provided a wedge portion 207. Rod 201 is attached to wedge portion 207 at 208, rod 202 is attached to rod portion 207 at 209, and rod 203 is attached to wedge portion 207 at 210. In this configuration rods 201, 202 and 203 are in a tapered position such that attachment points 204, 205 and 206 which join with seating portion 102 are relatively far from one another in comparison with attachment points 208, 209 and 210 which join wedge portion 207 which in turn connects with base portion 103.
In this example wedge portion 207 is attached to rods 201, 202 and 203 and is removably attached to base portion 103. Wedge portion 207 is configured to receive rods 201, 202 and 203 in a substantially T-shaped configuration and thus the cross-section of wedge portion 207 is substantially a T-shape.
In the present example, the central rod 202 is at a shallower angle than outer rods 201 and 203. In alternative embodiments more elongate members may be provided in addition to those shown in this example.
In this example the rods 201, 202 and 203 taper from the seating portion 102 to the base portion 103 at an angle of approximately 9°. The provision of the wedge portion 207 makes the chair more stable and also provides for stacking as is further described with reference to FIG. 4 .
A side view of chair 101 is shown in FIG. 3 , it can be seen in this Figure that central rod 201 is at a shallower angle than outer rods 202 and 203. In addition it is apparent that all three rods are attached to seating portion 102 at points substantially in front of the centre of gravity of the load of the chair when the chair is occupied.
When the chair is occupied and the rods 201, 202 and 203 are bearing a load, the rods deform into an inherent S-bend. If the load is greater on one side the chair will tilt and pivot with the load to support the new position. The resilience of the rods provides this adjustment and allows seating portion 102 to return to its default position when the chair is unoccupied.
A plurality of chairs according to an embodiment of the present invention are shown stacked in FIG. 4 . In this configuration, in order to stack the chairs a first chair is placed on a support surface and subsequent chairs have the wedge portion 207 removed from base portion 103 in order to stack then. The surplus base portions can in this example be stacked separately. Each chair in this example has an opening as is shown at 401 in FIG. 4 in seat portion 102. Seating portion 102 defines this opening in order to allow a connecting portion of another similar chair to pass through it in order to stack the chairs. In this example opening 401 is substantially T-shaped in order to allow the previously described three-rod configuration of the connecting portion to pass through. In alternative embodiments with alternatively arranged connecting portions the opening 401 would be adjusted accordingly. The wedge portions stack into one another as is shown at 402.
The tapered configuration of the rods provides for stacking in this type of arrangement and also increases stability of the chair.
An example of a bench-style configuration of chairs according to the present invention is shown in FIG. 5 . In this embodiment, instead of there being provided a single base portion as shown at 103 in earlier Figures there is provided a bench base at 501. Bench-style base portion 501 is configured to receive a plurality of wedge portions, shown here as 502, 503, 504 and 505 each supporting their own seating portion. Thus, seating portion 506 is supported by connecting portion 507 and wedge portion 502, seating portion 508 is supported by connecting portion 509 and wedge portion 503, seating portion 510 is supported by connecting portion 511 and wedge portion 504 and seating portion 512 is supported by connecting portion 513 and wedge portion 505. Advantages to the bench-type configuration include the facility to move a plurality of seating portions at the same time and the ease with which a uniform seating configuration may be achieved. Stacking is also facilitated in the bench-style configuration by seating portions and connecting portions being stacked into each other with the bench-style bases being stacked separately.
